Subdued beauty encapsulates redvein enkianthus cultivar 'Renoir'. It displays bright green foliage on red stems and bell-shaped, drooping, light yellow and pink blossoms in very early summer. In fall the leaves turn bold shades of yellow, orange and red before dropping away. The shrub's habit is upright but spreading. 'Renoir' originated in 1923 and was grown from seed from the University of Edinburgh. The cultivar name was assigned in the early 1980s by Rob Nicholson of the Arnold Arboretum, where it first grew.
A tree-like deciduous shrub from Japan, redvein enkianthus has simple and elliptical leaves with bristles on the edges and red leaf stems. In late spring to early summer, small, pendent, bell-shaped blossoms dangle from the branch ends. Blossoms are light yellow with pink lobes. They also are faintly and curiously scented. The brown, fall fruits that follow aren't ornamental, but the autumn foliage is beautiful. Once the leaves fall, the architecturally interesting, smooth, gray-brown branches and red twigs offer winter interest.
Plant 'Renoir' in partial sun to partial shade and acid to neutral soil that is rich in organic matter and perfectly drained. Even with the best care, it is a very slow grower. Culturally happy specimens will become larger in areas with milder winters. This shrub is a great focal plant for open woodland gardens with and understory of pretty perennials for shade. Some of its cultural equals include rhododendrons, azaleas and mountain laurels.
